Abstract
A method of stabilizing must and still and sparkling wines with respect to crystalline precipitation. Seed crystals of potassium hydrogentartrate are added to the products during processing to accelerate crystal growth. Since any calcium ions in the wine affect the crystallization of potassium hydrogentartrate, dipotassium DL-tartrate is also added to precipitate the calcium ions. The wine is cooled in a cooler and the colloids filtered out in a filter before the seed crystals are added and is finally stored at a low temperature in a tank. The precipitated crystals are removed in a hydrocyclone and 80% of them added along with dipotassium DL-tartrate to fresh wine that is to be stabilized. The added crystals are finely milled in colloid mills if necessary. The wine from the hydrocyclone is highly clarified in a centrifugal separator to eliminate any crystals not removed in the hydrocyclone.
